VoIP How to: IVR and Voicemail Example

From AAISP Support Site

(January 2016, Under construction)

Description of Requirements

Here is a mini example to set up a telephone service that provides these features:

  • Public telephone number offering two IVR options... (IVR is where you hear a recorded message which gives you options to press 1 for this, 2 for that, etc.)
    1. Option no. 1, to a VoIP Phone
    2. Option no. 2, redirect to a PSTN line during working hours and Voicemail at other times

We can represent this example as a simple flow chart:

Overview of configuration

We'll need three numbers for this example, let's assume our numbers are as follows:

  1. 123001, the main number that customers call. This will play the pre-recorded message and offer calles to press 1 or 2.
  2. 123002, the number that is used for the VoIP phone. Pressing 1 on the main number will call this number.
  3. 123003, the number that is used to redirect to an external number or go to voicemail. Pressing 2 on the main number will call this number.

We can expand the flow chart a little to better explain:

  3. Set a (secure) SIP Password
  4. Click the 'Incoming Tab'
  5. Set it to always to go voicemail
  6. Fill in the Also-rings so that 1 goes to 123002 and 2 goes to 123002.
  7. Enter a 'fail' number, as 123001 - this will be used as the default number to call if no digits are keyed by the caller
  8. Register a phone to the 'Main' number, dial 1571 and record your 'Please press 1 for Sales, 2 for support...' message
